I've always liked this mod for FO3 since I like being able to level-up to infinity.

I have no skill at all with coding or modding, would someone be willing to remake this or port this (if that is allowed)?

XFO drops the level cap, among many other changes. But if you just want the level cap gone, you can just use that esp

XFO-NV.com

EDIT: XFO also has an option to make perks count every level instead of every two, and to change the pacing. xD

I really liked this mod for FO3, but I'm sure a straight port would be tricky, seeing that you get a perk every two levels. Unsure as to how that'd work.

Use FNVEdit and search for 0013F401. Select it it the left window, right click and select "copy as override into", select "a new file", then change the "DATA -value" to whatever you want. You might have to use the console to remove some skill points before you get them maxed out.
After the patch FNVEdit will try to save the FalloutNV.esm when you exit, so uncheck that box. Ctrl-s or exiting saves you changes.
